Leaving aside broader changes, the following could be implemented
immediately and without revisiting prior design decisions:
1. As said by others, the search window should be at the top of the
page, above the 'What's New' section. The scope of the simple search
should be the entire archive.
2. The following sub-categories (or keywords) should be combined
because they are the same:
In Application:
devel, Devel, Development, development => Development
MIdi, midi => MIDI
util, Util, Utility => Utility
In Library:
devel, Development => Development
graphics, Graphics => Graphics
Regex, Regular Expressions => Regular Expressions
